Engine problems after oil change
 
I just finished changing oil and oil filter on my DRZ400SM. I've already done this a few times without any issues. However, after riding for 10 minutes after the oil change, I noticed how the engine would skip a beat from time to time at highway speeds. It's also easy to tell that there is something wrong because when trying to accelerate aggressively from low speeds, it feels jerky and is also easy to hear that the engine isn't accelerating smoothly.

When I got home (20 minutes ride), I noticed that the engine was very hot, much more than usual.

I'm not sure what's going on. I used the same oil filter and oil as usual (recommended Suzuki brand 4 stroke 10w-40 oil. The only thing I can think of is that, this time, I forgot to unscrew the oil dipstick before draining the old oil. Is it possible that because of that lack of vent (dipstick hole) I didn't drain all the oil before I added 2 quarts? would some extra oil have such a big impact?

thanks

Way too much oil can be bad. A little extra shouldn't hurt. How much does it show on the dipstick? If it's overfilled, you could drain a little, run it, and check it again. I don't know much about this particular bike. Is there any chance that the filter is installed incorrectly?

Bad plug or faulty lead

Or a bad oil filter. Or if it has variable valve timing, a piece of crud is lodged in the cam mechanism.

I wouldn't think the filter cover would fit on of or was backwards. does it really?

wow

I've seen it done on 4-wheelers a few times so it can be done and after 10 minutes it ain't gonna be pretty.

Oil filter backwards
 
I've seen it a few times myself on street bikes too. :deal

I think its a dirty air filter or bad plugs. When was the last time you cleaned or replace them.

That's not going to bake the top of the engine. Dry cam bearings sure would, though.

It has been a while since I had a DRZ400 but I believe 2 quarts is too much. Also I seem to remember there was a pretty specific way to drain the oil from that bike, I can't remember right now. But not removing the dipstick may have held a lot of oil back.

some bikes you can because of the indention in the filter for the spring that helps hold them in place.

The mention of those words makes me shiver

It's impossible to put the oil filter in backwards on this bike. The housing cover will not go back on. There are two drain plugs.
Was the frame AND crankcase drain plug removed?
